yes sounds like u got some soap left behind, and soap is NOT compatible with paint, you should use grease and wax remover sold in any auto paint store, but take two rags one for applying it onto body and the other one to wipe it off before it dries, cause wax and grease remover works by lifting dirt and wax off when its wet. After ure done with that buy one of those tack cloth, should be available at ur paint store, and use it just BEFORE u spray, it sticks dirt and lint to it off the surface and u get very clean surface.
